IMPROVEMENT IN PUM'PS.

,The Schedule referfed to in these Lettera Patent and making part.of thesame.

To all whom. 'it may concern:

Be it known that I, J Jsoon O.'JoYon, ot' tbe cityof Dayton, in thecounty of Montgomery, and State of Ohio, have invented certain new anduseful Improvements in Pumps; and I do hereby declare that the followingis a full, clear, and exact description thereof, reference being had tothe accompanying drawings, making a part of this specification, inwhich- Figure l represents a vertical cross-section of thevalve-chamber;

Figure-2, a vertical longitudinal section; and

Figure 3, a horizontal section on line V U.

Like letters refer to the same parts in all of the gures.'

My invention relates to( double or continuously-acting force-pumps, andconsists in a novel arrangement of the chambers, passages, and valves,and in placing the piston in the air-chamber, and the valves at one sidethereof, and in the'se'veral combinations hereinafterpset forth `andclaimedas new.

To. enable others skilled in the art to make and 'use my improved pump.vI will describe its constructio'and operation.

I make the principal portion, or frame-work, of my pump, A, theair-chamber. As shown, it is madein form of a barrel. Into this barrelor chamber, I insert the discharge-pipe G, 'which reaches nearly to thebottom thereof, so as to make it operate as an :tn-chamber. It isinserted one side of the centre or middle. In the centre, I place thepiston-chamber or cylinder B, which passes down to the bed-plate H, andis connected with or attached to it. On one side of this piston-cylinderI cast, or otherwise attach, a tube-paiiiton or cylinder, E, which opensinto the piston-chamber near the top, and also passes down to plate orbed H. Incylinder or chamber B, I place the piston or plunger D, whichis suitably packed, and is operated by the rod C. The bed or bottom Hcovers the bottom of the barrel A, and alsoextends out at the side, andVforms the lower half of the valve-chamber. It is also made of suicientdepth to contain the passages from the valves t0 the air-chamber orplunger, the partitionplate W, and the bottom plate I, being cast withH.

The space between plates Hand I- is divided into two equal or nearlyequal parts bythe partition-plate W, which leaves two passages, U and V.This plate, W, is simply a partition from the piston-cylinder to thevalve-chamber, as shown by the dotted lines in fig. 3. From that pointout, at H", it is double, with side inc lines, as shown in g. 1. Theseinclined sides form a chamber, x, between them for the entrance ofwater, which enters, at the opening T, into chamber z, and passesthrough the openings or passages P or'P',-ac cording to the stroke ofthe pump. These passages, P1 P', are closed by the action of the valvesNl and N. These valves,.N, are made to rock on the lower edges as shown,or they may rest on pivots b b, if desired, and in order to insure theiraction upon the return-stroke,

Vand prevent them from turning too far, small pins, a,

are attachedneartheir upper edges, which strike against the walls beforethe valves reach a vertical position,

so that they will always fall into the proper position, and they areheld down by the stopd, yor by other suitable meaus. Above these valves,I place the .doubleacting valve M, which rocks in plate L, or may besupported at the ends like the valves N. The plate L is attached to orcast with plates K, and on each side is provided with openings, O, whichare so arranged with valve M, that when one is closed the other will beopened. The passage Q opens up between plates K, and-may also open out,at the inner end, into the discharge-passage R, or open up and out bothaThe curvedplate J is bolted on above the plates K, as shown at iig. -1,\vl1ich leaves between 'them the chamber or discharge-passage It. Theair-chamber A and bed or plate H are fastened by bolts passing throughthe ilanches, as are also plates S and H, aud S and J. The other platesand partitions I usually cast in, As the pump is made of cast-iron, orother suitable metal, 'water may b'e admitted directly through the holeor opening T, but I usually place the pump above the well-cistern orreservoir, and screw in, or otherwise attach, a pipe to this opening,and extend such pipe down into the water, so that, so far as the firstor principal elevation of water is concerned, the pump is asuction-pump, and from the point of entrance into the pump out of it, aforce-pump, which makes it, in its usual action, a combined suction andforce pump.

In operation, the piston or plunger-rod O is operated by a lever, orcrank, or by any other suitable means. Two strokes will lill the pumpwith water. An up stroke of the piston will then draw the water throughvalve N', passage U, up into the cylinder B, and will force the water inthe upper portion of B, out through E', down through pipe E, opening F,passage V, openings O and Q, into passage It, and through R into theairchamberA, and from that into discharge-pipe C, from which it isdischarged with great force. A down stroke operates the same way, simplychanging the sides of the operation. All of the joints which are to betight, and the valves, are to be properly packed to Yprevent leakage.This construction makes a powerful pump, as I have found from testingit.

Having thus fully described my pump,

What I claim as new, and desire to secure by Le ters Patent, is v 1. Thecombination and arrangement of the valves N 'N' and M with the openingsU, V, and R, substantially as and for the purposes specified 2. Thecombination and arrangement of the pistonchamber B, piston or plunger D,tube or cylinder E, and discharge-pipe G, with the flues or. passages R,U, and V, substantially as specified.

3. The combination and arrangement of the airchamber A., piston-cylinderB, piston or plunger D, tiibe or passage E, and pipe G, with thepassages R, U, andV, valves N N and M, with their openings T,substantially as and for therpurposes specified,
